The two EL34 tubes in this' 'Matched Pair' were very closely matched as specified. They went into a guitar amp that had Electro Harmonix tubes originally installed from the factory. This amp, a Randall RG50TC, has controls for biasing the two output tubes individually. When the idle currents for each tube were adjusted to the same values, the negative voltage on the control grids were only 0.2 volts different. If you are an EL34 output tube fan, the Electro Harmonix brand is a winner. They have a very warm sound and will get 'bright' when you need them to. They are not 'boomy' or 'mushy' at all. Leads with distortion are very powerful and do not sound subdued or held back. They are also very clean if you adjust your amp for that Fender Twin Reverb sound. All in all, I would recomend these Electro Harmonix EL34's for any amplifier, guitar and HiFi Stereo alike. I have not found anything 'bad' about these tubes to speak of. They are Top Notch tubes at a descent price and excellent quaility. I realize that the sound of tubes in an amplifier have a lot to do with personal preference and the amplifier circuit design. In this case, the Electro Harmonix sounded better than the NOS tubes and other NEW brands that I have tried in THIS amp, other amps that I own, and amps that I have repaired for my friends & customers. I trust them totally. Morgan Musician Amplifier Technician BSEERead full review

I bought these tubes to repair and resurrect a vintage 1977 Music Man HD-130. The bakelite on the originals was blistered and they kept blowing fuses. After assessing the rest of the amp, I replaced the blown 12AX7 pre-amp tube then I shopped for these EL 34/6CA7EH power tubes here on eBay. After going through offer after offer of N.O.S. Sylvania, Sovtec and Westinghouse tubes (some of them used), I was getting disappointed at the prices. Then, I ran into this matched quad of Electro-Harmonix EL34/6CA7EH power tubes for $39.99 plus $4.10 shipping! I checked for reviews on line to see if this was a good quality tube and I found that is was. I received the tubes, installed them in the HD-130, fired it up and they worked great! This 40 year old Music Man amp is still kicking and will for many more years.Read full review

I had been paying more for NOS el34 tubes and Groove Tubes, but these sound as good or better for a lot less money. Buy these and you will be happy that you did.

Tubes look to be of good quality. They tested well, but I have not installed them in audio equipment yet and listened to them. At the price I paid, I was very happy to have found them, and will look for more deals like this.

These guys work great. Be sure to have your amp biased properly whenever replacing tubes.
